[求助]Gallery中播放视频的时候，拔掉TF卡

[Angleyuhj]

目前的代码是打算捕获EJECT消息处理。但是看log总是有如下

W/Vold    ( 2251): Failed to unmount /mnt/sdcard/extsd (Device or resource busy, retries 9, action 0)
……
E/ProcessKiller( 2251): Process com.cooliris.media (3654) has open file /mnt/sdcard/extsd/DCIM/.thumbnails/.thumbdata3-1763508120
W/Vold    ( 2251): Failed to unmount /mnt/sdcard/extsd (Device or resource busy, retries 2, action 1)
E/ProcessKiller( 2251): Process /system/bin/mediaserver (2256) has open file /mnt/sdcard/extsd/video/asf/bf3_faultline_ep3_windowsmedia9_13M_1080P_30fps_WMA2.asf
W/ProcessKiller( 2251): Sending SIGHUP to process 2256

就是在拔掉卡的时候，会判断进程打开的文件，重试10次后回把进程kill掉。
请问，我如何在收到EJECT消息的时候关闭这些打开的文件？如果处理？

拔掉TF卡 系统会发送一个广播，用Gallery 去捕获该广播 在自己播放视频代码处理该广播 不一定 非要在EJECT消息处理

现在有一种办法是重写一个写入流 重写wirte方法 fileOutPutSteam有一个getFD().sync(); 方法。调用它，然后抛异常。 不过现在还是会杀进程。还没解决。

你说的EJECT不知道是什么 我知道你的设备，读取tf之后，挂载的位置是/mnt/sdcard/extsd文件夹，你将tf卡拔掉之后，那么该文件夹将不再挂载tf卡，里面内容为空，你不能播放视频了！会报错的！

楼主我也遇见这个问题，现在解决没有

我也遇到同样的问题，系统直接杀进程，求解决 D/Vold ( 910): wuxingyu : vm handleBlockEvent D/DirVolume( 910): wuxingyu : handleBlockEvent begin D/MountService( 1276): sendStorageIntent Intent { act=android.intent.action.MEDIA_BAD_REMOVAL dat=file:///mnt/sdb/sdb1 (has extras) } V/MediaPlayerService( 919): [2] notify (0x1e70b50, 3, 2, 0) D/MountService( 1276): wuxingyu : use the mConnectorSpec[1] D/VoldCmdListener( 910): volume unmount_bad /mnt/sdb/sdb1 force_and_revert D/Vold ( 910): Volume sdb1 state changing 4 (Mounted) -> 5 (Unmounting) V/MediaPlayerService( 919): [2] notify (0x1e70b50, 3, 2, 0) I/USBReceiver( 1870): ---------USBReceiver---ACTION_MEDIA_UNMOUNTED-/mnt/sdb/sdb1 I/USBReceiver( 1870): mHandler == null V/MediaPlayerService( 919): [2] notify (0x1e70b50, 3, 2, 0) V/MediaPlayerService( 919): [2] notify (0x1e70b50, 3, 2, 0) W/Vold ( 910): Failed to unmount /mnt/sdb/sdb1 (Device or resource busy, retries 9, action 0) V/android hall( 1856): sdcard status changed!
